+# SYNOPSIS
+#
+#   AX_CHECK_GLU
+#
+# DESCRIPTION
+#
+#   Check for GLU. If GLU is found, the required preprocessor and linker
+#   flags are included in the output variables "GLU_CFLAGS" and "GLU_LIBS",
+#   respectively. If no GLU implementation is found, "no_glu" is set to
+#   "yes".
+#
+#   If the header "GL/glu.h" is found, "HAVE_GL_GLU_H" is defined. If the
+#   header "OpenGL/glu.h" is found, HAVE_OPENGL_GLU_H is defined. These
+#   preprocessor definitions may not be mutually exclusive.
+#
+#   Some implementations (in particular, some versions of Mac OS X) are
+#   known to treat the GLU tesselator callback function type as "GLvoid
+#   (*)(...)" rather than the standard "GLvoid (*)()". If the former
+#   condition is detected, this macro defines "HAVE_VARARGS_GLU_TESSCB".
